例程 1：Arduino — Wi-Fi 6 连接 + 网络质量检测

#include <WiFi.h>

const char* ssid = "YOUR_WIFI6_SSID";

void setup() {
  Serial.begin(115200);
  delay(1000);
  Serial.println("\n=== ESP32-C6 Wi-Fi 6 Test ===");

  // 优先使用 Wi-Fi 6 (802.11ax)
  WiFi.setMode(WIFI_STA);
  WiFi.begin(ssid, password);

  while (WiFi.status() != WL_CONNECTED) {
    delay(500);
    Serial.print(".");
  }

  Serial.println("\n✅ Connected!");

例程 2：MicroPython — GPIO + PWM 全测试

from machine import Pin, PWM, ADC
import time

# --- 输出测试：闪烁 LED ---
led = Pin(2, Pin.OUT)
for i in range(5):
    led.toggle()
    time.sleep(0.3)

# --- PWM 呼吸灯 ---
pwm = PWM(Pin(2), freq=1000, duty=0)
print("PWM breathing LED...")
for duty in range(0, 1024, 8):
    pwm.duty(duty)
    time.sleep(0.005)
for duty in range(1023, -1, -8):
    pwm.duty(duty)
    time.sleep(0.005)

# --- 按钮输入 + 中断 ---
button = Pin(9, Pin.IN, Pin.PULL_UP)
press_count = 0

def button_handler(pin):
    global press_count
    press_count += 1
    print(f"Button pressed! Count: {press_count}")

button.irq(trigger=Pin.IRQ_FALLING, handler=button_handler)

# --- ADC 读取 ---
adc = ADC(Pin(0))
adc.atten(ADC.ATTN_11DB)

print("Reading ADC (GPIO0)... Press Ctrl+C to stop.")
try:
    while True:
        val = adc.read()
        voltage = val * 3.3 / 4095
        print(f"ADC: {val:4d} | Voltage: {voltage:.2f}V | Button: {press_count}")
        time.sleep(0.5)
except KeyboardInterrupt:
    print("Done!")
    pwm.deinit()

例程 4：MicroPython — 802.15.4 / Zigbee 简单广播（实验性）

# 注意：ESP32-C6 的 MicroPython 802.15.4 支持可能受限
# 生产环境推荐使用 ESP-IDF 的 OpenThread/Matter SDK

import network

# Wi-Fi 作为 Matter Bridge
wlan = network.WLAN(network.STA_IF)
wlan.active(True)

print("Wi-Fi 6 / BLE 5.3 / 802.15.4 capable chip ready")

# BLE 初始化
import bluetooth
